Loading prediction method and electronic device using the same

Abstract

A loading prediction method, applicable to an electronic device, includes the following steps. Multiple resource loading records of the electronic device at multiple time periods are recorded, respectively. A predicted time point is received. A time difference between the predicted time point and a current time point is calculated. The predicted time point is greater than the current time point on a timeline. Whether the time difference is less than a threshold value is determined. A regression-based prediction according to the resource loading records is performed when the time difference is less than the threshold value. A clustering-based prediction according to the resource loading records is performed when the time difference is not less than the threshold value.
